Opencode

by SST

Opencode is an open-source, terminal/CLI-based AI coding agent built by the SST team (creators of the Serverless Stack framework). It provides a fully agentic coding loop — reading, editing, and creating files, executing shell commands, and iterating autonomously — with support for MCP (Model Context Protocol) to extend capabilities via custom tool servers. It is model-agnostic, allowing developers to bring their own API keys and choose from multiple LLM providers.
